Water Depth and Temperature Detector is designed for conducting hydrological and bathymetric surveys in rivers, lakes, and reservoirs

Water Depth and Temperature Detector utilizes the principle of acoustic reflection to collect water depth data. It features a measurement range of 0 to 80 meters with a blind zone of no more than 0.5 meters. It is suitable for use in both still water and flowing water (with flow velocities up to 5 meters per second). The device can simultaneously acquire data such as water depth, water temperature, and geographic coordinates, making it ideal for hydrological surveying and monitoring of river channels and reservoir areas.

Water Depth and Temperature Detector is a portable bathymetric instrument suitable for various aquatic environments, including reservoirs, lakes, rivers, and shallow coastal waters. It is designed for tasks such as hydrographic surveying, navigation and positioning, and field data collection. The instrument operates via ultrasonic ranging: an ultrasonic transducer is placed at a specific position below the water surface, and the device calculates water depth by measuring the round-trip time of an ultrasonic pulse, based on the known speed of sound in water. During its development, the device incorporated years of manufacturing expertise and design advantages from similar products. Its ultrasonic transceiver circuitry utilizes specialized large-scale integrated circuits, with a 99% surface-mount component (SMD) assembly rate. A full-color Chinese-language LCD screen displays measurement results directly. These features help minimize power consumption and ensure long-term, stable operation.

Water Depth and Temperature Detector can be mounted either inside or outside the hull of a small vessel and comes standard with a 10-meter cable. The display provides a comprehensive view of water depth, water temperature, latitude and longitude coordinates, movement speed, date and time, battery status, and Bluetooth connection status. Equipped with self-stabilizing measurement and rapid-tracking technologies, the device provides real-time, accurate data. A built-in watchdog circuit ensures stability and reliability during long-duration, continuous operation, while a high-precision internal clock maintains an annual error rate of within 3 PPM. The device offers 32 levels of adjustable transmit power and supports automatic gain control. It features a minimum display resolution of 0.1 mm, with a measurement accuracy of ±0.5% of the measured range. The system is easy to operate, highly portable, and offers fast response times. In practical application scenarios, Water Depth and Temperature Detector meets a wide range of operational requirements—including hydrological surveying, inspection of reservoir areas at hydroelectric plants, surveying of lakes and river channels, and environmental monitoring of water bodies. It is capable of reliably collecting water depth data even in flowing water, providing a solid foundation of data for tasks such as aquatic mapping, channel exploration, and water environment monitoring.
